hey every1, any1 know how to do statics questions? i have a few virtual work questions i have to get right by 2moro or i'll fail my course! please help...
There are several engineers here who can assist.
At What point from the left end should a uniform meter stick (cg.=50 cm mark and mass=68g) be supported so that is balances 10 g a the 0 cm mark, 40g at the 30cm mark, and 60 g at the 100 cm mark.
how can I draw a free body diagram?
a shelf is supported by two posts at a distance L apart from each other. three containers , each mass M are located of (1/5)L, (2/5)L, & (3/5)L from post A.shelf has a mass of M too.Express answer in M,L,g and numerical constants...
a) Find the upward force exerted by post A on the shelf ?
pls give a support, thanks

you have to sum all the forces in the y direction(M*9.8m/s). And then find the moment about point A. That will give you the reaction force at point A. Just use :
Sum of all forces in the y=0, where upward is positive
Sum of the moments about point A=0, where counter clockwise is positive.
Good luck. Let me know if it helps.
